Application filed April 20, 111925, Serial No. 24,654. Renewed April 12,I 1926.

The invention `contemplates .the provision of yan apparatusggt'or skimming y.molasses .by

percolating the molasses through 1a; perforated .trough which separates the entrancous matter, and conveys the latter fromthe apparatus to a suitable receptacle arranged to receive the same, the .trough-being moyable pto ultimately convey the pure molasses into a V,compartment from-which it can be;

drawn as desired.

The nature and :advantages of the inven-v tion -will be ybetter understood when the following detailed description is read connection with Ithe accompanying drawings, the invention residing yin .the construction, combination and .arrangement otparts as claimed. Y

In, the drawings forming part of thisv application, like numerals' of reference indicate similar pants inthe several views, `and wherein f Figure 1 is a sideelevation of the'apparatus.

Figure 2 .is a top lplan 4view `showing .by dotted -li-nes the position of thepertorated trough tor depositing the pure ymolasses into aV-storage compartment.

The :apparatus fformin-g fthe subject matter of the present invention may be constructed fromany suitable material and also vary in size and shape without departing from the spirit of the invention. The apparatus includes a tank 10 which is provided with a filling opening 11 which is normally closed by a stopper of any suitable design. Arranged on top of the tank 10 is a chamber or compartment 12 which communicates with the tank 10 through an opening 13. The communication however is controlled by a slide valve 14 which operates in suitable guides 15 and actuated by a float 16. The float is connected with the valve 14 by means of a suitable crank arm 17 journalled in a bracket 18 secured to the bottom of the compartment 12. Arranged alongside of the compartment 12 is an additional compartment or chamber 19 which is considerably larger than the compartment 12, and in which compartment 19 the molasses is conveyed after the extraneous matter has been completely separated therefrom. The chamber or compartment 19 is provided vwith an outlet nipple f2() throughayoke 23 which fis utilized to support .thel

latter uponthe pipe '21 `as shown in :Figure 3,' -Whi'le the :trough adjacent the other 12nd thereot is provided ,witha ldischarge Vnipple 24 which depen-ds `from the trough, `as

lshow-n. Projecting from the opposite sides oi? .this nipple 2a fare hooks 25 which are adapted to repose `upon* the upper edges voff theparticular compartment over which they trough is arranged, ,to assist in supporting thetrough in .position lfor use. As shown` in Figure 2fthe trough may be arranged @directly ,above the compartment 12, ywhich .position it (occupies while the molasses Iis Ybeing percolated .with a view of separatingthe extraneous gmatter (therefrom, :and subsequently ys liiztt it to the dotted line positionshow-nin ,F 15g-ure 2, which it occupies when it j'is desired to convey .the molasses Ito the storage compantrnent Q19.V The :trough is provided with a fialse perforated fbottom 26, sc that when the molasses fisconveyed tothe trou-gh, lit passes through Athe ,perforated bot-` tom :26, ancl.-,eventually yftndsgits way :through the Vnipple .-24 into the `compartmentior. chamber 12. The extraneous matter separated from the molasses vpasses over the perforated bottom 26, and subsequently passes from the trough through a spout 27, which projects laterally from the trough'as shown in F ig ure 2. The extraneous matter' is conveyed into a suitable receptacle not shown, butl which is adapted to be arranged beneath the spout 27. l

In practice, the tank 10 is filled with molasses through the opening 11, and the apparatus then is placed upon a suitable heater with a view of boiling the molasses. As the molasses boils, it passes upwardly through the pipe 21 to the perforated trough above described, wherein the extraneous matter is separated from the molasses as above described. The molasses passes through the perforated bottom 26 and is conveyed to the compartment or chamber 12. As this compartment illsup, the iioat 16 is raised, thereby opening the valve 14 to allow the molasses to pass from the compartment 12 back into the tank lO. As long as the perforated trough remains positioned above the compartment or chamber 12, the molasses will continue to `pursue this course until it is completely 'free of the extraneous matter. Then the trough is shifted to the position shown by dotted lines in Figure 2, so thatv when the molasses is again conveyed to the trough through the pipe 2l, it Willbe deposited Within the storage chamber or compartment 19, from YWhich it can be draWn in any desired quantity through the outlet nipp lVhile it is believed that from the foregoing description, the nature and advantages of the invention Will be readily apparent, I desire to have it understood that I do not limit myself to What is herein shown and described, and that such changesmay be resorted to When desired as fall Within'the scope of What is claimed.

' VHaving thus described the invention, I

claim: a

1. An apparatus of the character4 described comprising a liquid containing tank .adapted to be subjected to heat, an overflow pipe rising from the tank, a trough arranged above the tank to receive the liquid from said pipe and Y separate the extraneous rmatter from said liquid, a strainer arranged Within said trough in spaced parallel relation to theV bottom thereof, a compartment arranged above'the tank to receive the liquid from said trough, valve` controlled communication between the compartment and tank whereby the liquid is returned to the tank, and a spout projecting from said trough and through whichv the extraneous matter 'passes from the latter.

2. An apparatus of the character described comprising a liquid containing tank adapted to be subjected to heat, an overflow pipe rising from the tank, a trough arranged above the tank to receive the liquid from said pipe and separate the extraneous matter from the liquid, a oraminated element arranged Within the trough'in spaced parallel relation to the bottom thereof, a spout leading from the trough through which the extraneousmatter passes from the latter, a compartment arranged a-bove the tank and beneath said trough and communicating with the tank through an opening therein, said compartment being adapted to receive vthe liquid from said trough, and a float actuated valve controlling the communication between the compartment and said tank.

3. An apparatus of the character described, comprising a liquid containing tank adapted to be subjected to heat, independent compartments arranged above the tank side by side, one of said compartments communicat-l ingWith said tank, ar float actuated valve controlling said communication, an overflow pipe rising from thetank, a trough supported by said pipe and capable of lateral movement, said trough being Vnormally deposited above one of said compartments and adapted to receive the liquid from said pipe, and

separate the extraneous matter therefrom,

a screen arranged Within the trough in spaced parallel relation to the bottom thereof, said trough being designed to return the liquid to said tank through said compartment incident to the opening of said valve, a

spout projecting from said troughv and '53 Ythrough which the extraneous matter passes therefrom, and said trough being adapted to be arranged in communication` With the other of said compartment to iinally deposit Ehe liquid in the latterfor the purpose speci- In testimony whereof I aiiix my signature.
